Built-In Technology

Quixdown by TORAY
Traditional down had never been a viable option for mountain hunting, considering it loses all insulating properties when subjected to moisture. Not anymore. We treat each down cluster with DWR, so its impervious to moisture. We use the finest Polish goose down and perfect it with proprietary techniques to a remarkable 850+ fill power and 95:5 down to feather ratio.

Stunner Stretch Fabric by TORAY
Down insulation requires an added down-proof layer, or the down clusters and feathers can poke through the fabric. These added layers are noisy, bulky, and heavy. Stunner Stretch fabric is spec’d with a heat treatment process that creates a barrier down cannot penetrate. This fabric stretches as you move and offers the lightweight, quiet, and comfort hunters demand.

Once a fabric is soaked, insulation and breathability are compromised. K-DWR treatments bead and resist water, keeping it from penetrating the outer layer. This increased breathability and performance allow waterproof membranes to evaporate your sweat while blocking out moisture. K-DWR also enhances dry-time and protects from light rain or dew-soaked vegetation on non-waterproof products.
The Super Down PRO Pants are for the coldest hunts. They're sized to fit over your boots, base and mid-layers. They're ideal when temperatures plunge and low-level activity—like long glassing sessions or sitting in a stand. They're insulated with 3.2 oz of 850+FP Quixdown (Twice the down as ULTRA), making it KUIU’s warmest down pant.

Our Super Down products outperform the competition. We start with the best Polish goose down, which is cleaned, refined and processed by Kawada Feather in Meiwa, Japan. Their proprietary techniques perfect the down to a remarkable 850+ fill power and 95:5 down-to-feather ratio. Once cleaned, we treat the down with TORAY’s DWR, so each individual cluster is impervious to water; keeping its insulating loft even when wet.

The outer 30D Stunner Stretch nylon fabric is the perfect combination of performance and stretch. It's heat-treated to keep the down from migrating through the fabric, eliminating the need for noisy down-proof coatings. The fabric is also treated with TORAY K-DWR to repel light rain and snow.

The pants feature reinforced 70D x 80D paneling along the seat, knee and cuff for added protection. They compress and self-stow inside the left pocket for compact storage. They're so lightweight, you won’t regret having them in your pack.
